To all whom if may concern Be it known that I, GEORGE Fiscnaurr, a

citizen of the United States of America, and

a resident. of Chicago, in the county of Cook, State of Illinois, haveinvented certain new and useful Improvements in Folding Beds, of whichthe following is a specification.

This invention relates to the sofa type of folding beds, and has for itsobject to provide a simple and emcient structural arrangement andcombination of the folding bed members, in which said bed members areautomatically brought into an elevated, even and horizontal plane,during theopening operation of the parts, and which in the closingoperation are adapted to fold together in a'J manner which providesample space for the reception of the mattress, pillows and bed clothes,all as will hereinafter more fully appear.

In the accompanying drawings: Figure l, is an elevation of the presentSofa-bed mechanism, with an end arm or standard of the main frameremoved, the folding bed members beingl shown in their folded condition.Fig. 2, is an enlarged detail plan view, on line m-, Fig. l, of thelocking mechanism between the outer and central folding bed members.Fig. 3, is a detail transverse section of the same, on line mx, Fig. 2.Fig. 4, is a companion view to Fig. l, showing the folding bed sectionsin a partly unfolded condition. Figs. 5 and 5a, are Vdetached detailperspective views, illustrating the -pivotal connection of the sofaframe and the back cushion member. Fig. (5, is a companion view to Figs.l and 4l, showing the folding bed sections in a fully unfoldedcondition. Fig. 7, is an enlarged detail transverse section, on lineUL-m2, Fig. 6, illustrating the central folding bed member, itssupporting truck and accessories. Fig. 8, is an enlarged detaillongitudinal section of the same, on line authors, Fig. 7. Fig. 9, is asectional plan view, on line mthw, Fig. 6.

Similar' reference numerals indicate like parts in the several views.

Referring to the drawings, l represents the main frame of the sofa-bed,and comprising the usual upright end members or arms secured together inproper separated relation by the usual connecting rails and members. Inthe present construction the said end members are provided on theirinner faces with stationary horizontal track guidance and support of the3, which in turn supports described central folding bed member. Said endmembers are also provided with upright track or guide rails 4, for theguidance of the rear end of the hereinafter described rear folding bedmember. The movable support or truck 3, aforesaid, is of any usualskeleton construction, and is provided at its rear end withv trackwheels 5 having movementl on the horizontal track rails 2, aforesaid. Atits forward end said truck is provided with caster wheels 6, adapted toroll upon the ioor and support the forward end of the truck.

7 is a xed bracket member on the rear end of the truck 3, adapted forsupporting engagement with the frontportion of the rear folding bedmember, as hereinafter more fully described.

' 8 is the central folding bed member or section, upholsteredin anyusual manner, and connected to the truck 3, aforesaid, by a series ofradius links 9, so arranged that in an independent outward movement ofthe bed member 8 with relation to the truck 3, said bed member will atthe same time rise to an elevated plane, to form a portion of theelevated bed surface adapted to support the mattress, etc., when thesofa-bed is unfolded for sleeping purposes. In the folding together ofthe sofa-bed, the said bed member 8, as it is moved inwardly is adaptedto drop to its original position upon the frame of the truck 3, toprovide ample space'between said central bed member 8, and the front bedmember 16, for storage of the mattress and bed clothing;

l() is the rear folding bed member or sec.` tion, upholstered'in anyusual manner, and

rails 2, for the movable truck the hereinafter connected at its frontend to the rear end of the central bed member 8, in a pivotal manner,while at its rear end said bed member l0, is provided with lateral studsl1, which have sliding engagement in the grooves of the upright guiderails 4, before described. lith a view to limiting the travel of thestuds 11 in the aforesaid guide grooves, 'said grooves are provided withtop and bottom stops l2 and 13, as shown. In the present improvementsaid rear bed member 10, is connected in a pivotal and sliding manner tothe fixed bracket member 7 of the movable truck 3 before described, at apoint a short distance to the rear of its pointof pivotal connection tothe central bed member 8, and

preferably by means of a pivot pin or stud 14, and an elongated bearingslot 15, as shown. I

16 is the front folding bed member or section, upholstered in any usualmanner and having its rear portion connected in a pivotal manner by anintermediate bed section 17, to the front end of the central bed member8, aforesaid. Said front bed member 16, carries the usual sofa-bed seator cushion 18, and in the present improvement the rear end of said frontbed member 16, is connected to the front end of the supporting truck 3,before described, by radius links 19, as shown.

20 is a diagonally disposed spring secured at one end to the radius link19 of the front bed member 16, and at the other end to the radius link 9of the central bed member 8, at points removed from the points ofpivotal connection of said links to the truck 3. The function of saidspring 20, is to yieldingly resist a movement of the links 9 and 19 awayfrom each other, and aid in an easier operation of the parts in thefolding and unfolding movement of the bed members.

21 are folding legs secured as usual to the front edge of the front bedmember 16, to afford a support for such edge when the parts are unfoldedfor use as a bed.

' 22 is the front board of the base portion of the main frame 1, and inthe present construction said board 22, is attached to and carried bythe radius links 19 of' the front bed member 16, and is connected to therear edge of said bed member by a flexible web 23, to permit of thenecessary independent movements of the bed member 16 and front board 22,and provide a closure for the front of the sofa-bed, and conceal theparts and the articles inclosed, when the parts are folded together inthe form of a sofa.

24 are fixed standards near the rear end of the central bed member 8,and disposed at the respective sides of the same. In the presentconstruction the upper ends of said standards are formed with boltreceiving orifices 25, and outwardly inclined ends 26, which act asstrike plates for the hereinafter described spring actuated bolts, toguide the same into locking engagement in the orifices 25, aforesaid.

27 are the transverse bolts above referred to, arranged for -slidingmovement at the free end of the front bed member 16, and provided withthe usual actuating springs by which they are impelled outward forengagement with the above described orifices 25 of the standards 24,upon the central bed member 8.

28 is a pull rod or cord, preferably common to both bolts 27, so that apull on said rod or cord will cause a simultaneous retraction of bothbolts.

29 is the back member of the sofa, which in the present construction ispivoted to the upright end members of the main frame 1, so as to becapable of being swung upward and out of the way in the folding andunfolding movements of the bed members, and also of being swung backwardto the rear portion of the main frame to constitute the `head board ofthe bed, when thc bed members are unfolded, as illustrated in Fig. 6. Inthe present improvement the back member 29 is disposed a distanceforward of the upright guide tracks 4 of the folding rear bed member 10,to provide space between said rear bed member and said back member 29for the reception of a portion of the mattress and portions of thebedclothes.

30 are stops on the rear edge of the seat portion 18 of the sofa,against which the lower rear edge of the aforesaid back member 29 hasabutment when the parts are arranged as a sofa.

The operation of the present construction is as follows z-In anunfolding movement of the parts from the folded condition thereof,illustrated in Fig. 1, to the unfolded condition illustrated in Fig. 6,the operator initially draws the movable support or truck 3 outward fromthe main frame 1, into the position villustrated in Fig. 4, after whichthe spring actuated bolts 27 are withdrawn from their engagement withthe standards 24 of the central bed member 8, and the front bed member16, carrying the sofa seat 18, is tilted forward into the positionillustrated in Fig. 4. In such front tilting movement of the forward bedmember 16, the radius links 19 provide a fulcrum for said bed member 16,so that the same will cause a partial straightening of the intermediatebed section 17, and in addition will effect a partial upward and forwardmovement of the central bed member 8, upon its radius links 9, and inturn a partial downward movement of the rear bed member 10, toward ahorizontal plane, as illustrated in said Fig. 4. The further and finalmovement of said front bed member 16 to a horizontal plane,automatically raises the central bed member 8, and lowers the rear bedmember 10, to a common horizontal plane adapting the series of bedmembers to receive the mattress and accessories for sleeping purposes.During such opening movements of the parts, the sofa back 29 isinitially swung up out of the way, as illustrated in Fig. 4, andsubsequently lowered into the position illustrated in F ig. 6, toconstitute the head of the bed. The folding of the bed members to a sofacondition is the reverse to that just described in the unfoldingoperation.

In the closed condition of the present sofa-bed` as shown in Fig. 1, thefoot portion of the mattress is adapted to fold upon itself within thespace intermediate of the front bed member 16 and the central bed member8, While the other ,portion of the mattress will rest upon the rearfolding bed member 10, and in actual practice is usually tied orotherwise attached to the same.

With the present improved construction ample space is provided for thebed clothes,

pillows, etc., usually employed for sleeping" purposes.

Having thus fully described my said invention what I claim as new anddesire to secure by Letters Patent, is
